Oase AlGo Direct - Direct Blanketweed Control removes string algae quickly and reliably by releasing active oxygen. Algo Direct is extremely effective meaning the algae is killed off in the shortest imaginable time and can then be removed easily using a pond net. Any remaining algae is biologically decomposed by the action of the microorganisms.

Only use if the pH value is between 6.5 and 8.5 (6in1 QuickStick) and the KH value is above 3° dH. Immerse the test strips provided for approx. one second, shake lightly and read after one minute. At KH ≤ 3° dH (e.g. rainwater), harden first with Oase OptiPond. Remove as much algae as possible prior to application and then evenly scatter 50ml per 1000L of pond volume over the algae nests. Do not sprinkle on aquatic plants. Allow to take effect for 1 to 2 hours. Repeat dosage if algae start to grow again, but wait at least three days. Observe a safety interval of at least 12 hours in swimming ponds.
